In the neutral title complex, trans-bis(2,2'-iminodiethanol-N, O)bis(isothiocyanato)nickel(II), [Ni(NCS)(2)(C(4)H(11)NO(2))(2)], the isothiocyanate ions and the diethanolamine molecules act as monodentate and bidentate ligands, respectively. The Ni(II) ion exhibits a distorted octahedral configuration with crystallographically imposed inversion symmetry and N(NCS)-Ni-N(amine) and N(NCS)-Ni-O(amine) bond angles of 88.78 (10) and 89.44 (10) degrees, respectively. The Ni-N bond distances are in the range 2.069 (3)-2.096 (2) A. The molecules are linked by hydrogen bonds to form a three-dimensional infinite lattice.
